Specify the interval from when a path gets blocked to when a mirror gets split (suspended). Path Watch Time
This value must be within the range of 1 to 59 minutes, 1 to 23 hours, or 1 to 30 days. You
can specify a numeric value in Path Watch Time.
Make sure that the same interval is set to both the master and restore journals in the same
mirror, unless otherwise required. If the interval differs between the master and restore journals,
these journals do not suspend simultaneously. For example, if the interval for the master journal
is 5 minutes and the interval for the restore journal is 60 minutes, the master journal suspends
in 5 minutes after a path gets blocked, and the restore journal suspends in 60 minutes after
a path gets blocked.
Important: If you want a mirror to get split (suspended) immediately after a path gets blocked,
ask HP Technical Support to set the system option mode 448 to ON and set the system option
mode 449 to OFF.
